The electricity consumption of data centres is projected to more than double by 2030, according to a report from the International Energy Agency published today. The primary culprit? AI. Nature: The report covers the current energy footprint for data centres and forecasts their future needs, which could help governments, companies, and local communities to plan infrastructure and AI deployment. IEA's models project that data centres will use 945 terawatt-hours (TWh) in 2030, roughly equivalent to the current annual electricity consumption of Japan. By comparison, data centres consumed 415 TWh in 2024, roughly 1.5% of the world's total electricity consumption.

The projections largely focus on data centres, which also run computing tasks other than AI. Although the agency estimated the proportion of servers in data centres devoted to AI. They found that servers for AI accounted for 24% of server electricity demand and 15% of total data centre energy demand in 2024.

Children in a small Japanese town are obsessively collecting trading cards featuring local elderly men rather than popular fantasy creatures, helping bridge generational gaps in an aging rural community.

In Kawara, Fukuoka Prefecture, the "Ojisan TCG" (Middle-aged Man Trading Card Game) features 28 local men with assigned elemental types and battle stats. The collection includes a former fire brigade chief and a prison officer-turned-volunteer whose card has become so sought-after that children request his autograph.

Created by Eri Miyahara of the Saidosho Community Council, the initiative has doubled participation in town events. "We wanted to strengthen the connection between children and older generations," Miyahara told Fuji News Network. "So many kids are starting to look up to these men as heroic figures."

This week NASA "issued a solicitation for the next two private astronaut missions to the International Space Station," reports Space News. Scheduled after May of 2026 and then mid-2027, "These will be the fifth and sixth such missions to the ISS, part of a broader low Earth orbit commercialization effort by NASA with the ultimate goal of replacing the International Space Station with one or more commercial stations."

NASA's Space Station program manager calls the missions "a key part" of helping industry partners "gain the experience needed to train and manage crews, conduct research, and develop future destinations." In short, they see the missions "providing companies with hands-on opportunities to refine their capabilities and build partnerships that will shape the future of low Earth orbit." [NASA's call for proposals] offers an opportunity to have future missions commanded by someone other than a former NASA astronaut. While companies must propose a commander who meets current requirements, it can also propose an alternate commander who is a former astronaut from the Canadian Space Agency, European Space Agency or Japan Aerospace Exploration Agency with similar ISS experience requirements... ["Broadening of this requirement is not guaranteed," NASA warns.]

That could allow some former astronauts already working with commercial spaceflight companies an opportunity to command private astronaut missions. Axiom Space, for example, announced in July 2024 that former ESA astronaut Tim Peake had joined its astronaut team. That came after Axiom and the U.K. Space Agency signed a memorandum of understanding in October 2023 to study the feasibility of a private astronaut mission crewed exclusively by U.K. astronauts.
So far Axiom Space has been awarded all four private astronaut missions, according to the article, "flying one mission each in 2022, 2023 and 2024. Its next mission, Ax-4, is scheduled for no earlier than May."

But "While Axiom has little or no competition for previous PAM awards, it will likely face stiffer competition this time. Vast, a company also planning to develop commercial space stations, has previously stated its intent to submit proposals..."

U.S. stock markets suffered their worst day since the Covid pandemic after Donald Trump announced sweeping new tariffs, triggering a global selloff and wiping out $470 billion in value from tech giants Apple and Nvidia. From a report: The tech-heavy Nasdaq fell 6%, while the S&P 500 and the Dow dropped 4.8% and 3.9%, respectively. [...] Meanwhile, the US dollar hit a six-month low, going down at least 2.2% on Thursday morning compared with other major currencies and oil prices sank on fears of a global slowdown. Though the US stock market has been used to tumultuous mornings over the last few weeks, US stock futures -- an indication of the market's likely direction -- had plummeted after the announcement. Hours later, Japan's Nikkei index slumped to an eight-month low and was followed by falls in stock markets in London and across Europe.

Multiple major American business groups have spoken out against the tariffs, including the Business Roundtable, a consortium of leaders of major US companies including JP Morgan, Apple and IBM, which called on the White House to "swiftly reach agreements" and remove the tariffs. "Universal tariffs ranging from 10-50% run the risk of causing major harm to American manufacturers, workers, families and exporters," the Business Roundtable said in a statement. "Damage to the US economy will increase the longer the tariffs are in place and may be exacerbated by retaliatory measures."

"Microsoft built things. It broke things."

That's how the Seattle Times kicks off a series of articles celebrating Microsoft's 50th anniversary — adding that Microsoft also gave some people "a lucrative retirement early in their lives, and their own stories to tell."

What did they remember from Microsoft's earliest days? Scott Oki joined Microsoft as employee no. 121. The company was small; Gates was hands-on, and hard to please. "One of his favorite phrases was 'that's the stupidest thing I've ever heard,'" Oki says. "He didn't use that on me, so I feel pretty good about that."

Another, kinder phrase that pops to Oki's mind when discussing the international division he founded at Microsoft is "bringing home the bacon." An obsession with rapid revenue growth permeated Microsoft in those early days. Oki was about three weeks into the job as marketing manager when he presented a global expansion plan to Gates. "Had I done business internationally before? No," Oki said. "Do I speak a language other than English? No." But Gates gave Oki a $1 million budget to found the international division and sell Microsoft products overseas.

He established subsidiaries in the most important markets at the time: Japan, United Kingdom, Germany and France. And, because he had a few bucks left over, Australia. "Of the initial subsidiaries we started, every single one of them was profitable in its first year," he says...

Oki left Microsoft on March 1, 1992, 10 years to the day after he was hired.
Other memories shared by early Microsoft employees:

• One recent graudate remembered her parents in Spokane saying "I think that's Mary and Bill Gates' son's company. If that kid is anything like those two, that is going to be a great company,'" She got her first job at Microsoft in 1992 — and 33 years later, she's a senior director at Microsoft Philanthropies.

• The Times also interviewed one of Microsoft's first lawyers, who remembers that "The day the U.S. government sued Microsoft ... that was a tough day for me. It kind of turned my world upside down for about the next eight years."

• Microsoft senior VP Brad Chase remembers negotiating with the Rolling Stones for the rights to their song "Start Me Up" for the Windows 95 ad campaign. ("Chase is quick to dispel any rumor that Mick Jagger called up Bill Gates and got $12 million. But he won't say how much the company paid.")
  
  But Chase does tell the Times that Bill Gates "used to say all of the time, 'We're going to bet the company on Windows.' That was a huge bet because Windows, frankly, was a lousy product in its early days."

Automotive historian Dan Albert loves the "adorable tiny truck" he's driving. It's one of the small Japan-made "kei" pickups and minivans that "make up about a third of car sales in Japan." Americans can legally import older models for less than $10,000, and getting 40 miles per gallon they're "Cheap to buy and run... rugged, practical, no-frills machines — exactly what the American-built pickup truck used to be."

But unfortunately, kei buyers face "bureaucratic roadblocks that states like Massachusetts have erected to keep kei cars and trucks out of the hands of U.S. drivers." Several state departments of motor vehicles (DMVs) have balked at registering the imported machines, saying that they're too unsafe for American streets. Owners have responded with a righteous mix of good humor, lobbying and lawsuits... Kei trucks do not meet the Federal Motor Vehicle Safety Standards, or FMVSS — the highly specific rules US-market new cars must meet. But since 1988, the Imported Vehicle Safety Compliance Act has exempted vehicles that are at least 25 years old from these crash safety standards, allowing drivers to bring over vintage European and Asian market models...

Getting insurance coverage was the next barrier, as the company that had long been underwriting the Albert family's fleet also rejected me, forcing me to seek out a specialty "collector car" insurer. (I did eventually get regular coverage....) Maine, Rhode Island, New York, Pennsylvania, Georgia, Virginia, and Michigan also tightened their rules on registering small Japanese imports in recent years. The culprit, according to the auto enthusiast press, was the American Association of Motor Vehicle Administrators, the trade organization that serves as the lobbying and policy arm of DMVs across North America. Much of AAMVA's work involves integrating the databases of the 69 US and Canadian motor vehicle jurisdictions who are its members, so that a car stolen in one state can't be titled in another... The kei truck's regulatory troubles can be traced to a 2011 AAMVA report, "Best Practices Regarding Registration and Titling of Mini-Trucks," which called for outright bans and encouraged DMVs to lobby state legislatures to outlaw keis entirely.

The Insurance Institute of Highway Safety concurred, telling AAMVA that its recommendation did not go far enough: The IIHS said that keis should join the class of conveyances that the U.S. government calls Low Speed Vehicles, which are mechanically limited to 25 miles per hour or less and should be used only for short local trips on low-speed-limit roads because they can't protect occupants in the event of a collision with a regular vehicle... [But] By 2008, Japan's kei trucks did feature crumple zones and driver airbags in compliance with that country's safety standards...

Despite its name, the Imported Vehicle Safety Compliance Act that lets older cars into the US from overseas isn't really about safety: Car industry lobbyists secured passage of the law to protect dealer profits. Newer keis — which are banned — are safer and cleaner than the 25-year-old ones that can be imported now. (Battery-powered keis debuted in 2009.) But even mine has an airbag, front crumple zone, seatbelt pretensioners, and anti-lock brakes.
The article notes that kie fans have "a distinctly libertarian streak... Some owners I've talked to report forging titles, setting up shell companies in Montana and finding other means of skirting DMV rules."

U.S. robotics companies, including Tesla and Boston Dynamics, are urging lawmakers to establish a national robotics strategy to keep pace with China's aggressive investment in AI-driven robotics. The Associated Press reports: Jeff Cardenas, co-founder and CEO of humanoid startup Apptronik, of Austin, Texas, pointed out to lawmakers that it was American carmaker General Motors that deployed the first industrial robot at a New Jersey assembly plant in 1961. But the U.S. then ceded its early lead to Japan, which remains a powerhouse of industrial robotics, along with Europe. The next robotics race will be powered by artificial intelligence and will be "anybody's to win," Cardenas said in an interview after the closed-door meeting. "I think the U.S. has a great chance of winning. We're leading in AI, and I think we're building some of the best robots in the world. But we need a national strategy if we're going to continue to build and stay ahead."

The Association for Advancing Automation said a national strategy would help U.S. companies scale production and drive the adoption of robots as the "physical manifestation" of AI. The group made it clear that China and several other countries already have a plan in place. Without that leadership, "the U.S. will not only lose the robotics race but also the AI race," the association said in a statement. The group also suggested tax incentives to help drive adoption, along with federally-funded training programs and funding for both academic research and commercial innovation. A new federal robotics office, the association argued, is necessary partly because of "the increasing global competition in the space" as well as the "growing sophistication" of the technology.

The United States has won far more Nobel Prizes in physics, chemistry, and medicine than any other nation, with the UK and Germany following in second and third place, according to an analysis of nearly 900 prize-winning publications.

Universities account for roughly three-fourths of Nobel Prize-winning research, with a small number of elite institutions producing a disproportionate share of winners. Cambridge University leads with 32 prizes, followed by Harvard (22) and Columbia (13). While prizes are concentrated among researchers from the US, UK, and Germany, 43 countries have produced at least one scientific Nobel laureate.

Outside Europe and the Anglosphere, Japan leads with 11 prizes, while Argentina, China, and India have only one or two each. The average age of Nobel Prize winners has steadily increased from about 45 in the 1920s to 65 in the 2010s, though the age at which scientists perform their groundbreaking work has remained relatively constant at around 40.

"China is considering trying to blunt greater U.S. tariffs and other trade barriers," reports the Wall Street Journal, "by offering to curb the quantity of certain goods exported to the U.S., according to advisers to the Chinese government." Tokyo's adoption of so-called voluntary export restraints, or VERs, to limit its auto shipments to the U.S. in the 1980s helped prevent Washington from imposing higher import duties. A similar move from Beijing, especially in sectors of key concern to Washington, like electric vehicles and batteries, would mitigate criticism from the U.S. and others over China's "economic imbalances": heavily subsidized companies making stuff for slim profits but saturating global markets, to the detriment of other countries' manufacturers...

The Xi leadership has indicated a desire to cut a deal with the Trump administration to head off greater trade attacks... Similar to Japan, the Chinese advisers say, Beijing may also consider negotiating export restraints on EVs and batteries in return for investment opportunities in those sectors in the U.S. In some officials' views, they say, that might be an attractive offer to Trump, who at times has indicated an openness to more Chinese investment in the U.S. even though members of his administration firmly oppose it.
The article notes agreements like this are also hard to enforce, "particularly when Chinese companies export to the U.S. from third countries including Mexico and Vietnam."

The devastating impacts of the climate crisis reached new heights in 2024, with scores of unprecedented heatwaves, floods and storms across the globe, according to the UN's World Meteorological Organization. From a report: The WMO's report on 2024, the hottest year on record, sets out a trail of destruction from extreme weather that took lives, demolished buildings and ravaged vital crops. More than 800,000 people were displaced and made homeless, the highest yearly number since records began in 2008.

The report lists 151 unprecedented extreme weather events in 2024, meaning they were worse than any ever recorded in the region. Heatwaves in Japan left hundreds of thousands of people struck down by heatstroke. Soaring temperatures during heatwaves peaked at 49.9C at Carnarvon in Western Australia, 49.7C in the city of Tabas in Iran, and 48.5C in a nationwide heatwave in Mali.

Record rains in Italy led to floods, landslides and electricity blackouts; torrents destroyed thousands of homes in Senegal; and flash floods in Pakistan and Brazil caused major crop losses.

Storms were also supercharged by global heating in 2024, with an unprecedented six typhoons in under a month hitting the Philippines. Hurricane Helene was the strongest ever recorded to strike the Big Bend region of Florida in the US, while Vietnam was hit by Super Typhoon Yagi, affecting 3.6 million people. Many more unprecedented events will have passed unrecorded.

A SpaceX Falcon 9 rocket launched a four-member crew to the International Space Station on Friday night, paving the way for NASA astronauts Butch Wilmore and Suni Williams to return to Earth after being there for nine months due to issues with Boeing's Starliner capsule. Arrival is set for late Saturday night. The Associated Press reports: NASA wants overlap between the two crews so Wilmore and Williams can fill in the newcomers on happenings aboard the orbiting lab. That would put them on course for an undocking next week and a splashdown off the Florida coast, weather permitting. The duo will be escorted back by astronauts who flew up on a rescue mission on SpaceX last September alongside two empty seats reserved for Wilmore and Williams on the return leg.

Reaching orbit from NASA's Kennedy Space Center, the newest crew includes NASA's Anne McClain and Nichole Ayers, both military pilots; and Japan's Takuya Onishi and Russia's Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free. "Spaceflight is tough, but humans are tougher," McClain said minutes into the flight. You can watch a recording of the launch here.

Wilmore and Williams aren't stranded on the International Space Station, and they weren't abandoned, the astronauts reminded CNN in a rare space-to-earth interview last month. "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck -- and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.' That's what we prefer..."

An anonymous reader quotes a report from Ars Technica: Researchers at Harvard University led the study, and it included nearly 58,000 adults in Japan who were followed for up to a year using a database of medical records from routine checkups. Researchers found that when people switched from being nondrinkers to drinkers during the study, they saw a drop in their "bad" cholesterol -- aka low-density lipoprotein cholesterol or LDL. Meanwhile, their "good" cholesterol -- aka high-density lipoprotein cholesterol or HDL -- went up when they began imbibing. HDL levels went up so much, that it actually beat out improvements typically seen with medications, the researchers noted.

On the other hand, drinkers who stopped drinking during the study saw the opposite effect: Upon giving up booze, their bad cholesterol went up and their good cholesterol went down. The cholesterol changes scaled with the changes in drinking. That is, for people who started drinking, the more they started drinking, the lower their LDL fell and higher their HDL rose. In the newly abstaining group, those who drank the most before quitting saw the biggest changes in their lipid levels.

Specifically, people who went from drinking zero drinks to 1.5 drinks per day or less saw their bad LDL cholesterol fall 0.85 mg/dL and their good HDL cholesterol go up 0.58 mg/dL compared to nondrinkers who never started drinking. For those that went from zero to 1.5 to three drinks per day, their bad LDL dropped 4.4 mg/dL and their good HDL rose 2.49 mg/dL. For people who started drinking three or more drinks per day, their LDL fell 7.44 mg/dL and HDL rose 6.12 mg/dL. For people who quit after drinking 1.5 drinks per day or less, their LDL rose 1.10 mg/dL and their HDL fell by 1.25 mg/dL. Quitting after drinking 1.5 to three drinks per day, led to a rise in LDL of 3.71 mg/dL and a drop in HDL of 3.35. Giving up three or more drinks per day led to an LDL increase of 6.53 mg/dL and a drop in HDL of 5.65. The study has been published in JAMA Network Open.

Watch the "Blue Ghost" lunar lander attempt its moon landing.

The actual landing is scheduled to happen at 3:34 a.m. Eastern time, according to CNN, while "The first images from the mission should be delivered about a half hour after..." Success is not guaranteed... [B]roadly speaking, about half of all lunar landing attempts have ended in failure. Jason Kim, Firefly's CEO, told CNN in December that his company's experience building rockets has given him a high degree of confidence in Blue Ghost's propulsion systems. "We're using (reaction control system) thrusters that we've built, developed in-house, that are designed by the same people that design our rocket engines. That reduces risk," Kim said. "All that gives us high confidence when we have people that do rocket engines really, really well — some of the best in the world."
But the New York Times notes that Blue Ghost, built by Austin, Texas-based Firefly Aerospace, is just one of three robotic spacecraft "in space right now that are aiming to set down on the moon's surface." Blue Ghost has performed nearly perfectly. For the first 25 days, it circled Earth as the company turned on and checked the spacecraft's systems. It then fired its engine on a four-day journey toward the moon, entering orbit on February 13. The spacecraft's cameras have recorded close-up views of the moon's cratered surface...

On the same SpaceX Falcon 9 rocket that launched Blue Ghost to orbit was Resilience, a lunar lander built by Ispace of Japan. The two missions are separate, but Ispace, seeking a cheaper ride to space, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload... Although Resilience launched at the same time as Blue Ghost, it is taking a longer, more fuel-efficient route to the moon and is expected to enter orbit around the moon in early May.
The third lunar lander heading to the moon is Athena (from Intuitive Machines), which launched Thursday on a SpaceX Falcon 9 rocket, "marking the first time humanity has had three lunar landers en route to the Moon at the same time," according to a statement from the company. Space.com notes that "To date, just one private spacecraft has ever landed successfully on the moon — Intuitive Machines' Odysseus, which did so in February 2024." Athena launched with several other spacecraft last night, including Odin, a scouting probe built by the asteroid-mining company Astroforge, and NASA's water-hunting Lunar Trailblazer. Lunar Trailblazer is also moon-bound, though it's headed for orbit rather than the surface...

The number of babies born in Japan last year fell to the lowest level since records began 125 years ago as the country's demographic crisis deepens and government efforts to reverse the decline continue to fail. Financial Times [non-paywalled source]: Japan recorded 720,988 births in 2024, according to preliminary government figures published on Thursday. The number has declined for nine straight years and appears to be largely unaffected by financial and other government incentives for married couples to produce more children.

An anonymous reader quotes a report from Fortune: Starting in April, the Tokyo Metropolitan government, one of the country's largest employers, is set to allow its employees to work only four days a week. It is also adding a new "childcare partial leave" policy, which will allow some employees to work two fewer hours per day. The goal is to help employees who are parents balance childcare and work, said Tokyo Gov. Yuriko Koike. "We will continue to review work styles flexibly to ensure that women do not have to sacrifice their careers due to life events such as childbirth or child-rearing," Koike said in a speech during the Tokyo Metropolitan Assembly's regular session, the Japan Times reported.

Moving to a four-day workweek could help address some of the core issues associated with Japan's heavy work culture, which can especially weigh on working women. The gap between men and women when it comes to housework is one of the largest among OECD countries, with women in Japan engaging in five times more unpaid work, such as childcare and elder care, than men, according to the International Monetary Fund. More than half of women who had fewer children than they would have preferred said they had fewer children because of the increased housework that another child would bring, according to the IMF. In some cases, moving to a four-day workweek has been shown to improve housework equity. Men reported spending 22% more time on childcare and 23% more time on housework during a four-day workweek trial conducted across six countries by 4 Day Week Global, which advocates for the issue.

It would take a major societal change for the four-day workweek to catch on more broadly, but years of experiments have shown that working one day less a week improves employee productivity and well-being, said Peter Miscovich, the global future of work leader at real estate services company JLL. "The upside from all of that has been less stress, less burnout, better rest, better sleep, less cost to the employee, higher levels of focus and concentration during the working hours, and in some cases, greater commitment to the organization as a result," Miscovich told Fortune.

Electricity demand is set to increase sharply in the coming years as people around the world use more power to run air conditioners, industry and a growing fleet of data centers. From a report: Over the next three years, global electricity consumption is set to rise by an "unprecedented" 3,500 terawatt hours, according to a report by the International Energy Agency. That's an addition each year of more than Japan's annual electricity consumption.

The roughly 4% annual growth in that period is the fastest such rate in years, underscoring the growing importance of electricity to the world's overall energy needs. "The acceleration of global electricity demand highlights the significant changes taking place in energy systems around the world and the approach of a new Age of Electricity," Keisuke Sadamori, IEA's director of energy markets and security, said in a statement. "But it also presents evolving challenges for governments in ensuring secure, affordable and sustainable electricity supply."

Nintendo is facing an uphill battle in its U.S. patent fight against Palworld creator Pocketpair, with the United States Patent and Trademark Office rejecting 22 out of 23 patent claims, according to gaming news site GamesFray.

While Nintendo has successfully obtained one patent covering character capture mechanics, the company is seeking additional protections related to gameplay features like "smooth switching of riding objects." An attorney representing Nintendo has requested a meeting with patent examiners to discuss the rejected claims. The patent dispute, which began in Japan where Nintendo is seeking $66,000 in damages, could have broader implications for the gaming industry if successful

Several countries are seeing a decline in PhD enrollments as high living costs, stagnant stipends and limited job prospects deter students from pursuing doctoral degrees. Australia recorded an 8% drop in domestic PhD enrollments from 2018 to 2023 despite population growth of 7%, while Japan's numbers fell to 15,014 in 2023 from 18,232 in 2003, data from education authorities showed.

PhD stipends have failed to keep pace with rising costs. In Australia, doctoral students receive about A$32,000 ($20,000) annually, below minimum wage, while Brazil only increased its graduate grants last year after a decade-long freeze.

The trend reflects broader concerns about academic careers becoming increasingly precarious, said Claudia Sarrico, a project lead at the Organisation for Economic Co-operation and Development in Paris. Some countries are taking steps to address the issue. Japan's education ministry plans to provide additional funding for doctoral students, while Brazil's 40% increase in graduate grants in 2023 has led to a slight uptick in enrollments.

Today T-Mobile announced what they're calling "the next big thing in wireless" — T-Mobile Starlink. But the real surprise is "The beta is now open for absolutely everyone — yes, even Verizon and AT&T customers — to register for free access until July."

And, as they explained to Americans watching the Super Bowl, "If you can see the sky you're connected." Now in public beta, this breakthrough service, developed in partnership with Starlink, uses straight-out-of-a-sci-fi-movie satellite and mobile communications technology to help keep people connected — even you, Verizon and AT&T customers — in the more than 500,000 square miles of the country unreached by any carrier's earth-bound cell towers. That's nearly the size of two Texases...! The beauty of the service is its simplicity: users don't need to do anything out of the ordinary. When a user's cell phone gets out of range of a cell tower, the phone automatically connects to the T-Mobile Starlink network. No need to manually connect. Messages are sent and received just as they are today on a traditional network, even group texts and reactions. And it works on most smartphones from the last four years. It's not limited to a few smartphones or operating systems...

The beta is free until July at which point T-Mobile Starlink will be included at no extra cost on Go5G Next (including variations like Go5G Next 55+), T-Mobile's best plan. Business customers will also get T-Mobile Starlink at no extra cost on Go5G Business Next, first responder agencies on T-Priority plans and other select premium rate plans. T-Mobile customers on any other plan can add the service for $15/month per line. Through February, T-Mobile customers who have registered for the beta can secure a $10/month per line Early Adopter Discount, 33% off the full price.

AT&T and Verizon customers hate dead zones, too

When your service is amazing and different, you want as many people to try it as possible. T-Mobile is giving AT&T and Verizon customers the opportunity to try out T-Mobile Starlink satellite service on their existing phones... During the beta period, Verizon and AT&T customers can experience T-Mobile Starlink text messaging for free, and once the service launches in July, it will be available for $20/month per line... More details and consumer registration can be found here.

A Vision for Universal Coverage

As T-Mobile and Starlink continue to work towards eliminating mobile deadzones, the companies welcome wireless providers from around the world to join their growing alliance, which aims to provide reciprocal roaming for all participating carriers. So far, KDDI (Japan), Telstra (Australia), Optus (Australia), One NZ (New Zealand), Salt (Switzerland), Entel (Chile & Peru), Rogers (Canada) and Kyivstar (Ukraine) are among the providers that have signed on to join the cause and launch satellite-to-mobile technology. Learn more about the alliance and how providers can join at direct.starlink.com.

Twisting two atomically thin sheets of graphene enables "a host of exceptional properties," writes MIT News, "including unconventional superconductivity." (Which makes this graphene "a promising building block for future quantum-computing devices.")

And now "We find the superfluid stiffness to be much larger than expected..." a team of researchers reported this week in Nature. Hackaday explains that "Part of the problem has been that it is hard to make large pieces of multi-layer graphene. By creating two-ply pieces and using special techniques, an international team is finding that quantum geometry explains how graphene superconductors resist changes in current flow more readily than conventional superconductors."

Or, as Science Alert puts it, "Forced to run a labyrinth of carbon atoms uniquely arranged in twisted stacks, electrons do some rather peculiar things." Researchers from the University of British Columbia in Canada, the University of Washington and Johns Hopkins University in the US, and the National Institute for Materials Science in Japan recently discovered a strange new state of matter in the dynamics of currents flowing through layers of graphene.

The findings confirm predictions on how electrons ought to behave when squeezed into crystalline arrangements, and may contribute fresh ideas on how to achieve reliable approaches to quantum computing or reveal ways to develop room-temperature superconduction... Graphene has been increasingly seen as something of a wonder material over recent decades, its lattice of carbon atoms connected in a way that leaves spare electrons to leap about like tokens in a game of quantum checkers. Physicists have consistently bent the rules of this game, finding new and unusual ways to alter properties of resistance or coordinate into exotic states. For these reasons, graphene has become a perfect playground to search for clues on low-resistance conductivity or test the boundaries of various quantum effects.
This week MIT research scientist Joel Wang (a co-lead on the study) said "There's a whole family of 2D superconductors that is waiting to be probed, and we are really just scratching the surface." New Scientist explores where their research could lead: Why do cold thin sheets of carbon offer no resistance to electric currents? Two experiments are bringing us closer to an answer — and maybe even to practical room-temperature superconductors... Past experiments have shown that very cold stacks of two or three layers of graphene can superconduct, or perfectly conduct electricity without resistance and energy loss, if some of the sheets are rotated by a special angle. But why this happens remained mysterious... [B]oth teams had to innovate a setup where the tiny graphene flakes were exposed to microwaves while the researchers slowly varied properties like temperature, which must be kept very low for superconductivity to occur at all...

"We are finding interesting laws which seem to emerge in both these material systems. Maybe what we are uncovering is something deeper," says [Harvard postdoctoral researcher Abhishek Banerjee]. Both teams are planning on performing similar experiments with other very thin superconductors.
